文摘

Aerobic granules formed from conventional activated sludge in synthetic media. Protein content of tightly bound EPS had greatest influence on granule properties. 73% color and 68% COD removal of dyeing wastewater achieved with adapted granules. Dye removal occurred during aerobic phase when %GR of aerobic granules was above 50%. Exposure of granules to dyeing wastewater enhanced EPS production but reduced %GR.
